First of all, could you please clarify what do the abbreviations MTWTF and MWF mean?

Second, what should I do to enter the game? I have 2.7j version (AFAIU it is compartible) and an AutoHost Client installed.

I've got to say that the main appeal to me of the beginners game is playing against real beginners without the strain of tutelage, or the pressure of playing an expert like ccmaster. I understand it can be useful, but it might be more entertaining with just newbs. There's frequently other games where beginners can play with a more mixed crowd. Also I think ccmaster wanted to play but not teach, which doesn't make sense to me since he is very good. Just my 2 cents.
